Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent energy saving, and in particular relates to an intelligent energy-saving control system applied to a mold temperature controller. Background Art

[0002] Temperature control is an essential part of the control system in the mold temperature control machine. The mold temperature is monitored in real time through a temperature sensor, and the temperature data is fed back to the controller. The controller automatically adjusts the power of the heating or cooling system according to the difference between the preset temperature value and the actual temperature value to achieve the purpose of accurately controlling the mold temperature. At present, the mold temperature control machines commonly used in the market are: 1. The traditional closed impeller centrifugal circulating water pump has low operating efficiency, resulting in increased working energy consumption. 2. The traditional stainless steel tubular heater combined with the heating barrel has low heating efficiency and long heating time, resulting in increased working energy consumption. 3. The traditional tubular cooler has a slow heat exchange speed, and heat is lost during the exchange process, resulting in increased working energy consumption. 4. It is impossible to automatically control the precise flow and pressure. The only solution is to install too many pressure relief devices and heat medium recovery pipelines, which leads to heat medium loss and high power consumption.

[0003] Therefore, based on the above-mentioned defects of the existing mold temperature controller, it is necessary to improve the existing mold temperature controller. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies of the existing technology and provide an intelligent energy-saving control system for a mold temperature controller, thereby reducing energy consumption, saving energy and reducing emissions, and being green and environmentally friendly.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an intelligent energy-saving control system applied to a mold temperature controller, comprising a mold, a cooling water tank, a circulation mechanism, a heating mechanism and a cooling mechanism, wherein pipes are connected between the mold, the cooling water tank, the circulation mechanism, the heating mechanism and the cooling mechanism, and the mold, the cooling water tank, the circulation mechanism, the heating mechanism and the cooling mechanism are communicated with each other through pipes.

[0006] As an optimal intelligent energy-saving control system for a mold temperature controller according to the present invention, the circulation mechanism is mainly composed of a cooling water inlet, a first filter, a one-way water supply solenoid valve, a high-temperature three-dimensional flow impeller centrifugal circulation pump, a high-pressure protector, a first pressure display, a first one-way flow control valve, a first ball valve, a heat medium outlet, a heat medium return port, a second filter, and a second ball valve.

[0007] As a preferred intelligent energy-saving control system used in a mold temperature control machine of the utility model, a low-pressure protector is also installed on the surface of the connecting pipe between the first filter and the one-way water supply solenoid valve, and the heat medium outlet and heat medium return port are connected to the mold through a pipe.

[0008] As a preferred intelligent energy-saving control system used in a mold temperature controller of the utility model, the heating mechanism is mainly composed of a cast copper heater, a first exhaust solenoid valve, an over-temperature controller, and a first temperature sensor.

[0009] As a preferred intelligent energy-saving control system used in a mold temperature control machine of the utility model, the cooling mechanism is mainly composed of a second temperature sensor, a shell and tube cooler, a second exhaust solenoid valve, a second pressure display, a pressure relief solenoid valve, a third filter, a cooling solenoid valve and a cooling water return port.

[0010] As a preferred intelligent energy-saving control system used in a mold temperature control machine of the utility model, a second one-way flow control valve is also installed on the surface of the connecting pipe between the shell and tube cooler and the first filter and the one-way water supply solenoid valve, and the cooling water return port and the cooling water inlet are connected to the cooling water tank through a pipe.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model adopts a high-temperature three-dimensional flow impeller centrifugal circulation pump, which divides the three-dimensional space inside the impeller infinitely. By analyzing each working point in the impeller flow channel, a complete and real mathematical model of the fluid flow in the impeller is established. The structure of the impeller blades can adapt to the real flow state of the fluid, and can control the velocity distribution of all fluid particles inside the impeller, correcting the unreasonable phenomenon of increased power consumption caused by high resistance, and significantly improving the operating efficiency.

[0013] In addition, the use of cast copper heaters has the characteristics of high thermal conductivity, short heating time, uniform hot surface temperature, high thermal insulation performance and long life, which significantly improves heating efficiency and reduces energy consumption.

[0014] At the same time, the use of shell and tube coolers can effectively reduce heat exchange time, avoid excessive loss of heat medium, and reduce energy consumption.

[0015] Finally, by automatically controlling the pressure and flow, the circulation pump and heater can be prevented from operating at high power for a long time, thus achieving the goal of energy saving while accurately controlling the temperature of the equipment.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1 The utility model provides the following technical solutions: an intelligent energy-saving control system applied to a mold temperature controller, comprising a mold 27, a cooling water tank 28, a circulation mechanism, a heating mechanism and a cooling mechanism. A pipe 29 is connected between the mold 27, the cooling water tank 28, the circulation mechanism, the heating mechanism and the cooling mechanism. The mold 27, the cooling water tank 28, the circulation mechanism, the heating mechanism and the cooling mechanism are communicated through the pipe 29.

[0024] In the embodiment, a high-temperature three-dimensional flow impeller centrifugal circulation pump 5 is used to infinitely divide the three-dimensional space inside the impeller. By analyzing each working point in the impeller flow channel, a complete and real mathematical model of the fluid flow in the impeller is established. The structure of the impeller blades can adapt to the real flow state of the fluid, and can control the velocity distribution of all fluid particles inside the impeller, correcting the unreasonable phenomenon of increased power consumption caused by high resistance, and significantly improving the operating efficiency.

[0025] In addition, the cast copper heater 7 is adopted, which has the characteristics of high thermal conductivity, short heating time, uniform hot surface temperature, high thermal insulation performance and long life, which significantly improves heating efficiency and reduces energy consumption.

[0026] At the same time, the shell and tube cooler 19 is used to effectively reduce the heat exchange time, avoid excessive loss of heat medium, and reduce energy consumption.

[0027] Finally, by automatically controlling the pressure and flow, the circulation pump and heater can be prevented from operating at high power for a long time, thus achieving the goal of energy saving while accurately controlling the temperature of the equipment.

[0028] Example 2

[0029] See also Figure 2 The circulation mechanism mainly consists of a cooling water inlet 1, a first filter 2, a one-way water supply solenoid valve 4, a high-temperature three-dimensional flow impeller centrifugal circulation pump 5, a high-pressure protector 6, a first pressure display 10, a first one-way flow control valve 11, a first ball valve 13, a heat medium outlet 14, a heat medium return port 15, a second filter 16, and a second ball valve 17.

[0030] In the preferred embodiment, a low-pressure protector 3 is further installed on the surface of the communication pipe 29 between the first filter 2 and the one-way water supply solenoid valve 4 , and the heat medium outlet 14 and the heat medium return port 15 are connected to the mold 27 through the pipe 29 .

[0031] In the embodiment, in the circulation mechanism, the cooling water in the cooling water tank 28 enters the cooling water inlet 1 through the pipe 29, and then enters the first filter 2 from the cooling water inlet 1. At the same time, the one-way water supply solenoid valve 4 is opened to allow the cooling water to enter the high-temperature three-dimensional flow impeller centrifugal circulation pump 5. Subsequently, the cooling water flows into the cast copper heater 7 through the high-temperature three-dimensional flow impeller centrifugal circulation pump 5. The cooling water flows into the mold 27 through the cast copper heater 7 through the pipe 29. The first pressure display 10 displays the real-time heat medium pressure of the circulation pipeline. The first one-way flow control valve 11 automatically controls the heat medium flow rate of the pipeline. At the same time, the first ball valve 13 is opened to allow the cooling water to flow into the heat medium outlet 14 through the pipe 29, and then be injected into the cooling water channel of the mold 27 through the heat medium outlet 14, reflux through the heat medium return port 15, and then pass through the second filter 16 and the second ball valve 17 to enter the shell and tube cooler 19. Most of the heat medium continues to pass through the circulation pipeline to form a separate heat medium cycle.

[0032] Example 3

[0033] See also Figure 1 and 2 : The heating mechanism is mainly composed of a cast copper heater 7, a first exhaust solenoid valve 8, an over-temperature controller 9, and a first temperature sensor 12.

[0034] In the embodiment, in the heating mechanism, when the internal temperature of the cast copper heater 7 rises and generates high pressure, the first exhaust solenoid valve 8 automatically opens to exhaust, the over-temperature controller 9 plays a protective role when the temperature is too high, the first temperature sensor 12 monitors the real-time temperature of the heat medium in the pipeline, and the control system automatically adjusts the heating power of the heater.

[0035] Example 4

[0036] See also Figure 1 and 3 The cooling mechanism mainly consists of a second temperature sensor 18, a shell and tube cooler 19, a second exhaust solenoid valve 20, a second pressure display 21, a pressure relief solenoid valve 23, a third filter 24, a cooling solenoid valve 25 and a cooling water return port 26.

[0037] In the preferred embodiment: a second one-way flow control valve 22 is also installed on the surface of the connecting pipe 29 between the shell and tube cooler 19 and the first filter 2 and the one-way water supply solenoid valve 4, and the cooling water return port 26 and the cooling water inlet 1 are connected to the cooling water tank 28 through the pipe 29.

[0038] In the embodiment, in the cooling mechanism, the heat medium passes through the second filter 16 and flows through the pipe 29 to the second ball valve 17, and then the second temperature sensor 18 monitors the real-time temperature of the heat medium in the circulation pipeline. When the heat medium temperature is lower than the working requirement, the heater is heated and operated, and circulates through the shell and tube cooler 19 according to the process of "Example 1"; when the heat medium temperature is higher than the working requirement, the second one-way flow control valve 22 opens, and automatically controls the flow of cooling water to be injected into the shell and tube cooler 19, and the cooling system works. When the internal pressure of the cooler is too high, the second exhaust solenoid valve 20 automatically opens for exhaust, and the second pressure display 21 displays the real-time heat medium pressure of the circulation pipeline. When the pressure is too high, the pressure relief solenoid valve 23 automatically opens, and a small amount of heat medium passes through the third filter 24 and the cooling solenoid valve 25 from the cooling water return port 26 to the cooling water tank 28, thereby achieving the purpose of energy and water saving.

[0039] It should be noted that when the first pressure display 10 shows that the pressure of the circulation pipeline is insufficient, the one-way water supply solenoid valve 4 is opened to supply cooling water into the circulation pipeline. The one-way function is to prevent the heat medium from flowing into the circulation pipeline.

[0040] In addition, the first pressure display 10 displays the real-time pressure of the circulation pipeline, and the first one-way flow control valve 11 automatically controls the flow of the heat medium in the circulation pipeline. The high-temperature three-dimensional flow impeller centrifugal circulation pump 5 and the cast copper heater 7 are operated at the most reasonable operating power, thereby saving energy consumption.

[0041] Finally, when the cooling mechanism is working, the second one-way flow control valve 22 automatically uses the most reasonable opening and closing state to avoid excessive cooling water flow and rapid temperature drop that causes the heater to frequently perform heating work, which can effectively control and save energy consumption.

[0042] It should be further explained that the equipment described in the article all belongs to existing mature technologies. Among them, the models of the first filter 2, the second filter 16 and the third filter 24 are: SBL-BM; the model of the cast copper heater 7 is: CBDJ cast copper pipe heating equipment; the model of the shell and tube cooler 19 is: BEM-325; the above equipment can be customized into the required appearance according to actual conditions.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
